The government of South Sudan has refused to renew the Block B3 oil exploration licence previously held by Oranto Petroleum, citing prolonged inactivity and failure to meet key contractual obligations.
According to the Ministry of Petroleum, the company did not carry out seismic surveys, drill exploratory wells, or fulfil required financial commitments since acquiring the licence in 2017.
The 24,000-square-kilometre oil block, which was awarded with a pledged investment of $500 million, remained largely undeveloped for nearly a decade despite being considered a potentially resource-rich area.
Officials stated that the block is now open to new investors and will be reassigned to companies with stronger technical expertise, financial backing, and clear operational timelines.
The decision forms part of a broader push by South Sudan to enforce stricter compliance standards within its oil and gas sector and improve the pace of exploration activities.
The move adds to a series of regulatory setbacks for Oranto Petroleum across Africa, where several of its exploration rights have faced cancellations or disputes in recent years.
In Senegal, authorities previously revoked offshore exploration rights linked to the company after reported failures to provide financial guarantees and limited field activity over several years.
The offshore block near Dakar had been viewed as promising but remained largely unexplored despite early geological indications of hydrocarbon potential.
Additional challenges have also been reported in other African markets, including disputes involving partners in Equatorial Guinea and restructuring arrangements in São Tomé and Príncipe, where operational control shifted following revised joint venture agreements.
Industry observers note that Oranto has traditionally focused on acquiring early-stage exploration assets across Africa, often partnering with larger oil companies for development.
However, recent licence withdrawals highlight a growing trend of stricter enforcement by African governments, who are increasingly demanding faster exploration progress, stronger financing assurances, and clearer development commitments from oil companies.
